' SPECIFICATION forming part of Letters Patent no. 754,309, dated March s, 1904.

I Application filed July 20, 1903. Serial No. 166,376. '(No model.)

known as side nut-locks in which the 1001iing appliance is applied to one side of the'nut for the purpose of holding the same immovable upon the bolt.

- My improved construction of nut-lock is particularly adapted for use .uponrailroad and bridge constructions; but it is obvious that it can be employed in other constructions wherein it is desired to lock a series of nuts upon their respective bolts;

The invention. consists in the employment of a waSher-platehaving a plurality of boltopenings intermediate its ends and forwardlyextending projections adjacent its end, one

Iprojectionbeing in the form of a hook and the other in the form of an apertured lug, and

.in the employment of a locking-plate which is adapted to extend along the sides of the nuts; said locking-plate having an elongated aperture adjacent one end which is-ada'pted to engage the hook-shaped lug and an aperture adjacent the opposite end throughwhich the apertured lug is adapted to pass and a cotter-pin or key for the purpose of securing the free end of the locking-plate.

The invention consists also in certain details I l o n u of constructlon and novelties of combination,

all of which will be fully described hereinafter and. pointed out in the claims. 7

In theidrawings forming part of this specification, Figure 1 isa perspective view showing. the practical application of my nut-lock. Fig. 2 is a view showing the manner of connecting the locking-plate to the washer-plate. Fig. 3 is a detail perspective view of the washer-plate. Fig. t is a detail view of the locking-plate. Fig. 5 is a view showing the cotter-pin or key., Fig.,6 is a top plan view of a portion of the nut-lock, the web of the rail being shown in horizontal section. i

Washer-plate serving as a fishplate, saidwasher-plate having a series of holt-openings D intermediate its ends and. through which the bolts pass. A hook-shaped projection E extends forwardly from the washenplate D at one end thereof, and a verticaily-apertured lug F extends forwardly from the oposite end of the plate, said lug having the horizontal shoulders F.

G indicates the locking-plate, which is cut away upon the lower side intermediate its ends, as shown at G, and is constructed with an elongated opening (Er -adjacent one end and a square aperture G adjacent the opposite end. The locking-plate G is adapted to be arranged upon the nuts as shown in Fig. 1, and in order to connect the locking-plate to the washer-plate the said locking-plate is first turned to a position substantially at right angles to the WitSllGPPliLhB, so that the hookshaped lug E will pass freely through the elongated aperture Gr". The plate G is then turned down and the lug-F forced through the aperture G and a cotterepin or key H passes through the vertical aperture F of the lug F,

and it will be noted that the locking-plate will rest upon the top sides of'all the nuts and also against the sides of the end nuts. It will be impossible for the locking plate to become disengaged, and so long as the locking-plate remains in place it will be impossible for the nuts to turn upon the bolts. The lockingplate can be quickly and easily removed whenever it is'desired to remove the nuts.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A nut lock comprising a washer-plate having a plurality of bolt-openings intermediate its ends, a hook-shaped projection adjacent one end, and a vertically-apertured projection adjacent the opposite end and a locking-plate having apertures adjacent its oppo site ends, one of said apertures being elongated and a pin or key adapted to be passed its opposite ends, one of said apertures be I through the apertured projection, substaning elongated, and a cotter-pin adapted to be tially as described. passed through the vertical aperture of the 2.
